Take a look at include/linux/init.h. There you can find the macros for
declaring various init functions. They all go into special sections. The
rest is linker magic (e.g. arch/x86/kernel/vmlinux.lds{,.S}).

It's, too, in the init.h. There are two definitions of module_init()
depending on whether MODULE is declared or not. The first definition is
accompanied by a useful comment about where the init function is called in
either case.
